Description

Satellite L-band synthetic aperture radar backscatter data from 1996 and 2007 (from JERS-1 and ALOS PALSAR respectively), were used with field data collected in 2007 and a back-calibration method to produce biomass maps of a 15000km2 forest-savanna ecotone region of central Cameroon. The relationship between the radar backscatter and aboveground biomass (AGB) was strong (r2=0.86 for ALOS HV to biomass plots, r2=0.95 relating ALOS-derived biomass for 40 suspected unchanged regions to JERS-1 HH)....[Show more]
